选取23颗双峰轮廓脉冲星，考察脉冲星射电辐射锥成分的谱行为. 通过对前导和后随成分峰值强度比与频率的关系进行幂律谱拟合，给出了前后两部分的相对谱指数. 结果显示，大多数脉冲星的相对谱指数集中分布在零附近, 这表明，前导和后随成分的辐射本质上没有差别；相对谱指数的近似高斯分布显示出，其辐射部位离辐射束中心距离之差具有一定的随机性.

The relative spectra of the leading and the trailing components aremeasured and investigated for 23 conal-double pulsars. The data is fitted with simple power-law function. For most pulsars, therelative spectral indices concentrate in a narrow range near zero.The result suggests that the leading and the trailing components come from the same emission ring. The scatter of therelative spectral indices is probably caused by unsymmetricallocation of the leading and trailing components with respect to thebeam center for each individual pulsar.
